Oral administration of spiropent (clenbuterol), 20 mcg on waking in the morning and 40 mcg before sleep, daily for 2 months, was studied in 34 patients, 19 males and 15 females, aged between 27 to 73 years (mean 47.8 +/- 17.5), who had chronic reversible airways obstruction as defined by the A.T.S.'s criteria. Assessments were made before and after the trial by monitoring lung function parameters and patient's comment on efficacy, side effects and comfort. Except 5 patients, 2 suffering from severe headache and 3 from poor control of asthma who had withdrawn from this study after one week of treatment, all patients completed the trial. Six out of 29 patients who completed the trial needed additional steroid treatment and 9 needed beta 2-agonist inhalation during the treatment period. The results showed improvement of FEV1 more than 15% in 21 patients (72%), FVC in 17 patients (59%) and PEFR in 20 patients (69%). These increases were significant (p less than 0.0001). However, only 12 patients (41%) had marked subjective improvement at the end of treatment. Cough (21%), headache (10%), nausea (7%) and dizziness (3%) were the commonest side-effects. No clinical or statistical difference was found in changes of vital signs and laboratory parameters. In conclusion, clenbuterol was effective and well-tolerated in the majority of patients enrolled in this study with minimal side-effects and good compliance. It may be used for long-term treatment of chronic reversible airways obstruction at lower cost.

To date, there is no effective pharmacologic treatment for Chagas' cardioneuropathy, one of the most common causes of congestive heart failure and sudden death in the world. Fifty-eight adults with positive serology for Chagas' disease and abnormal autonomic nervous system tests participated in this placebo-controlled clinical trial with Cronassial (mixed gangliosides), 40 mg daily intramuscular injection for 4 or 8 weeks. We measured postural response (heart rate, systolic and diastolic arterial blood pressure changes in response to standing); heart rate changes induced by cough and hyperventilation reflex tests; dizziness on standing; number of stress-induced arrhythmias; and periodic acid-Schiff (PAS)-positive T-lymphocyte percentage in blood samples. Cronassial is safe and significantly improves systolic blood pressure (p = 0.050) and double product responses to postural stress (p = 0.028), hyperventilation heart rate response (p = 0.007), frequency of dizziness episodes (p less than 0.001), number of arrhythmias (p = 0.033), and percentage of PAS-positive T-lymphocyte counts (p less than 0.001) compared with placebo.

Data from clinical trials with benazepril suggest that the safety profile of benazepril is similar to that of other angiotensin-converting enzyme (ACE) inhibitors. Treatment-related side effects occurred in 20% of benazepril-treated patients and in 18% of patients receiving placebo. The most commonly reported side effects with benazepril were headache, dizziness, and fatigue. The incidence of side effects was not affected by the degree of hypertension, age, gender, race, dosage, or the degree of renal impairment. Side effects believed to be related to the pharmacologic action of ACE inhibitors as a class include symptomatic hypotension, which occurred at a relatively low rate with benazepril, and hyperkalemia and elevation of serum creatinine, which occurred to the same extent with benazepril as has been noted with other ACE inhibitors. The mechanism of cough as an ACE inhibitor side effect is unknown; the incidence was similar to that with other ACE inhibitors. Rash and taste disturbance have occurred rarely with benazepril. The incidence of neutropenia and of proteinuria was the same in both the benazepril and placebo groups. Renal failure in hypertensive patients treated with benazepril has not been reported. Overall, benazepril is generally well tolerated by hypertensive patients. The incidence of most side effects is comparable to that with other ACE inhibitors and placebo.

Clinical and epidemiological features of 72 cases of boutonneuse fever, detected from 1979 to 1986 at the "Hospital del Insalud de Cartagena" (Murcia), are reviewed. The most important clinical features are commented on (fever, rash, tache noire), as well as the less important (dizziness, cough, conjunctivitis, sensorial changes). Several epidemiological factors were analyzed, temperature having been found to be the most significant in our area. The complications observed mainly affected patients with risk factors (senility, thrombocytopenia, hyponatremia, high blood pressure) being particularly severe in a patient who developed lethal DIC and in another 2 who developed pulmonary thromboembolism. The prophylactic measures suggested were the strict control of animals susceptible to parasites and organizing of disinfestation campaigns in the endemic areas.

An open multicenter trial was performed in 242 subjects with chronic obstructive airways disease between August 1987 and April 1989. Two hundred thirty-six subjects were evaluated with regard to safety (m 137, f 99, mean age 49.4 (18-77) years) and 204 subjects with regard to therapeutic efficacy (m 120, f 84, mean age 49.2 (18-77) years). Twelve micrograms (one puff) formoterol was given by metered-dose inhaler twice daily. Investigations were performed at days 0, 14, and subsequently in monthly intervals. Twenty-one patients (10.3%) were sufficiently treated by formoterol alone. One hundred and eighty-three (89.7%) required additional medication, which could be reduced in 90 cases (45.6%). Initially symptoms were present in 201 of 204 patients. At 1 year, 43 patients (21.1%) were symptom-free. At day 0 32.4% of the patients felt "very good" or "good." At 1 year the rate increased to 68.1%. Raw decreased from 0.52 +/- 0.26 (0.06-2.11) kPa.L-1.S at day 0 to 0.33 +/- 0.14 (0.06-0.88) kPa.L-1.S (= -43.5%) at 1 year. FEV1 increased from 1.90 +/- 0.80 to 2.54 +/- 0.97 L (33.7%). The global assessment of therapeutic efficacy was classified as "very good" in 51% (patients) and 47% (doctors), respectively, and as "good" in 38.7% and 42.0%, respectively. Tolerability was "very good" in 82.3% (patients, doctors), and "good" in 12.7% (patients) or 13.7% (doctors). The treatment did not influence blood pressure or heart rate. Twenty-nine patients (12.3% of 236) reported unwanted 39 side effects, such as tremor (6.36%), headache (2.54%), dryness of the mouth (1.27%), cough (0.85%), and dizziness (0.85%).(ABSTRACT TRUNCATED AT 250 WORDS)

During 1988, an endemic outbreak of aseptic meningitis was noted in the Kaohsiung area. Throughout the year, a total of 89 cases were identified by cerebrospinal fluid (CSF) examination at the Pediatric Department of Kaohsiung Medical College. The peak incidence was from June to October. Scattered cases still occurred during November and December. The male to female ratio was 1.7:1 and the age distribution ranged from 1 month to 15 years old. Two peaks of age distribution were observed; one in infancy and the other in the 4-7 year old age group. Most of them exhibited fever (94.4%), headache (68.9%), and vomiting (68.5%). Other associated symptoms and signs included neck stiffness, sore throat, cough, Brudzinski's sign, abdominal pain, seizure, dizziness, rhinorrhea, diarrhea, Kernig's sign, skin rash, hyperemic conjunctiva, apnea, and oral ulcers. Most of them had CSF white blood cell (WBC) counts less than 1000/mm3, normal or mild elevated protein, and normal CSF/plasma sugar ratio. Three patients were found to have a virus in their CSF without pleocytosis. Virus isolations from CSF throat swabs and/or rectal swabs were performed in 65 patients, half of them (35/65, 53.8%) had positive results including echovirus type 9 (sixteen), echovirus type 30 (eighteen), and adenovirus type 3 (one). Echovirus type 9 was predominant during July and August whereas echovirus type 30 became predominant after September. All patients recovered spontaneously without any sequelae.

Approximately 25,000 recorded visits between primary care physicians and adults aged 25 and older in the 1985 National Ambulatory Medical Care Survey were analyzed to study the relationship between patient age and selected process measures of the physician-patient encounter. Multiple presenting complaints and visit diagnoses both rose with age. In spite of this evidence of increased complexity of elderly patients, mean visit length for cough, dizziness, diabetes, and general medical examinations failed to rise, with longest visits tending to be among middle-aged patients. Performance of blood pressure examinations, rectal examinations, breast examinations, pelvic examinations, and Papanicolaou (Pap) smears on patients presenting for general medical examinations tended to decline beyond age 65. These results suggest that individual office visits for older patients may be less comprehensive than those for younger adults.

In a multicenter study in general practice, the tolerability and safety of ramipril alone and in combination with a low dose of furosemide were assessed in moderate hypertension. After a placebo run-in period involving 770 patients, 661 were included in the active treatment period and received ramipril alone (2.5-5 mg/day). After 6 weeks, the nonresponders entered in a double-blind period and they received daily ramipril 10 mg or ramipril 5 mg in combination with furosemide 20 mg. In this hypertensive population, the adverse events more commonly reported were headache, cough, dizziness, asthenia, cramps diarrhea and nausea, but not all these events were related to ramipril. There was seemingly a relation between cough prevalence and rampiril dosage; an increased incidence was also observed during the outbreaks of flu-syndrome in our country. 38 patients discontinued the active treatment due to non-serious adverse events, mainly cough, dizziness or diarrhea. No serious adverse drug reaction was observed. Laboratory data (blood cells count, electrolytes, serum creatinine, fasting blood glucose, apolipoproteins AI and B) remained most commonly unaffected. In moderate hypertension in general practice, this study confirms that ramipril is well tolerated, especially with regard to the class effects of the angiotensin converting enzyme inhibitors.

Health and environmental assessment of the consequences of accidental contamination of an area in the Negev desert is described and the effects of exposure to bromine vapor in 6 persons evaluated. They were only mildly affected during the acute spillage of the bromine, with some respiratory symptoms and first and second degree skin burns of small exposed areas on the legs. All were treated in hospital and were released within 1-4 days. 6-8 weeks later they demonstrated a complex array of complaints, including cough, shortness of breath, chest tightness, eye irritation, headache, dizziness, fatigue, memory disturbances, sleep and sexual disturbances. These complaints could not be substantiated by objective clinical or laboratory examination. There was thus obvious magnification of the complaints 1-2 months after the accident.

The authors report an episode of mass psychogenic illness exacerbating respiratory symptoms in military recruits. The epidemic occurred over a 10- to 12-hour period in September 1988, in a group initially complaining of cough and pleuritic chest pain. More than 1,800 men were evacuated from their barracks because of a suspected toxic gaseous exposure. Approximately 1,000 recruits developed at least one new symptom, 375 were evacuated by ambulance to receive further medical evaluation, and at least eight were hospitalized. Air sample testing from the area was unremarkable, and there were few abnormal physical examination or laboratory findings. The epidemiologic investigation included a questionnaire administered 2 weeks after the epidemic to 1,000 of the recruits involved. A total of 55% of those who completed the questionnaire reported the onset of at least one new symptom after supper, with at least 25% reporting the new onset of cough, light-headedness, chest pain, shortness of breath, headache, sore throat, or dizziness. A total of 18% received further medical evaluation. The development of new symptoms and the receipt of further medical evaluation were associated with evidence of physical stress, mental stress, and awareness of rumors of odors, gases, and/or smoke. This epidemic was unique because of its size and its occurrence in an all-male population.
